Perry Hall High School Shooting Victim In Critical Condition

One student was shot Monday morning at Perry Hall High School in Baltimore County, authorities confirmed to CBS Baltimore.

Authorities confirmed to CBS Baltimore that the shooter was a student at the school.

The shooter is in custody.

While authorities have yet to confirm either boy's identity, The Baltimore Sun is reporting a 15-year-old boy is in police custody.

The injured student, a 17-year-old boy, has been taken to Maryland's Shock Trauma Center. Officials have not commented on the boy's condition but CBS Baltimore reported the injured student has been taken to Shock Trauma and is in critical condition.

CBS Baltimore reported the student was shot in the back in or near the cafeteria.

"We do not believe at this time he was targeted," Baltimore County Police Chief Jim Johnson said in an early-afternoon press conference.

One of the students said a person dressed in all black entered the cafeteria and shot three times, according to a parent who called in to CBS Baltimore.

An instructor grabbed the suspect after the first shot was fired, Johnson said. A second shot was fired when teachers grabbed the suspect.

”I heard two large bangs and I saw people running and it was chaos and everybody ran outside, and the principal told us to stay in the grass area and away from the cafeteria," another student witness told CBS Baltimore.
